I have tried everything I can think of, but when I click on google+ on the home screen or google play in multiplayer I get an error, "Sign in error: Sorry, we're unable to sign you into Google Play Games. Please ensure you have an internet connection and a Google+ account enabled on this device." I have triple checked I have both enabled and tried a number of other things to. What gives? I bought this game for the multiplayer, and I live on a college campus so wifi games don't apparently work on WPA-enterprise.Nexus 4, Andorid 4.4.2
